At about 1150 UTC on 23rd July 2022, I tuned in to PBS Gannan broadcasting in the Tibetan language on 3990 kHz.
The broadcast was coming from the Hezou 15 KW transmitter in China.
The overall reception of PBS Gannan was good. At 1200 UTC interference was experienced from China National Radio on 3985 kHz.
Below is a short video showing my reception of PBS Gannan.
